Specification of Letters Patent.

Patented April 16, 1907.

Application filed December 27, 1906. Serial No. 349,702.

To all wil/0m t may concern:

Be it known that I, SAMUEL S. CHILDS, Va citizen of thefUnit'ed States, residing at Bernardsville, in the county ofSonierset and State of New Jersey, have invented certain new and useful improvements in Spring- Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others vskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to letters of reference marked thereon, which form a 'part oi this specification.

i 5 The present invention is of a class of springwheels, and is an im rovenient on the form of wheel shown and escribed in my a plication, Serial No. 336,534, filed Septe'ni )er 28,

'1906, and is designed to provide a wheel of this kind that has a vbody portion supplied with a felly and havingr a rim at a distance therefrom and with iiat springs secured at their centers to the felly an d having the ends in Contact with the inside of the rim.

z 5 The present improvement consists in springs, preferably ofy a spiral form, that fit in between the ends of the flat springs, take up the motion between these springs to furnish more resiliency, and also to act as transmitgo' ting means when powe'ris applied to either the rim or the body ortion of the wheelA to insure the turning o t-he body portion andA the rim together. y

The invention is illustrated in the accom panying drawings, in which- Figure 1l is aside view of part of a wheel ol' my 'nem construction. broken away at one point, showing the rim in section. Fig. 2 is a section online 2,2 in Fig. 1. '4o The' body portionof the wheel embraces a hub 10, spokes 1]., and a folly 12. These elements are commento all wheels and may -be of the usual constructions. Outside ofthe felly and removed therefrom by a considerable spaee is a ri1n`13, provided with a tire portion 14. Secured to the rim 13. is a guard- .plate 16, held securely by means of the bolt 17 -andprojeeting over slightly onto the felly 12 under normal conditions.

The-sprin r members in my wheel are preferably straioiht and fiat, as at 1S, and the ends 19 are in engagement with the inner edge` of the rinif13, which is irovided with a band 20, which is made of 'a iard substance, such as steel', to take up the wear of the springs. I

form on the ends 19 of one of the springs 18as shoulder 21, this shoulder on adj aeent springs. lnclosing to a slight' extent on one side a .spring 22, which is preferably spiral and is arranged in areeess 23 in thel rim. I prefer to back up the springs on each side with a disk or plate 24 to center the springs and to not allow a rocking contact between the shoulder 2l ,and the springs 22. Different forms of springs from` the syle shown in the drawings can be supplied in place of the springs 22, and the particular formof contact means between the springs-18 and the springs 22 can be -departed from. If this wheel is used on the driving-axle of a motorear-for instance, when power is applied to the body portion of the wheel-the springs 18 will all .be thrust in one direction and each spring onone end willy come in contact with one of the springs 22, and the vehicle will start without any shock or jar, and when the i spring is compressed and the power is still 'applied the spring 22 in its compressed shape will act to transmitpower and e a transmitting medium between the springs 18 and the riin 13.

If no power-transmission is calledfor, the springs 22 will be compressed when a weight is placed .on a vehicle to which the wneel is attached, and thus allow the easy sliding. or working of the ends `19 of the springs 18 on the inner surface of the rim. It will thus be seen that the springs 22 have an oiiice as spring members between thel ends of the springs 18 and also as spring members between the ends ci' the springs 18 and the opposed wall of the recess 23 in the rim 13. Having thus described my invention, what i claim is- 1. A spring-wheel comprising a body portion having ai'clly, a rim surroundingr the felly at a distance therefrom forming a circular space between them, a set of ilat straight springs arrangedin this space and secured at their centers to the felly, and having their ends in engagement with the inside of the rim, the rim being provided with recesses on its inner face between the adjacent ends of the springs, and a second set of springs, one in each recess and bearing on the ond walls of the recess, and also being in contact with the ends of the adj acont llat springs.

2. A spring-wheel comprising a body portion havino a elly, a rnn surrounding the ielly at a distance therefrom 'forming a space between them, and being provided with reeesses on its inner face, a set of at straight springs in the space between the felly and the nm, and having their ends alongside the end SAMUEL S.

In testimony than claim the fegoing I have hereunto set my hand this 24th day of December, 1906.
